How do I make my cisco soho 91 router's communicate with d-link router on different subnet?

Hi...

I've tried this for hours :) hope to get an expert response from anyone that is willing to help me out. "I'm not a cisco guy, first week playing with it" so be gentle.

I have a Cisco SOHO 91 router and a D-Link WBR-1310 (wireless).
I've successfully setup them to run on the network, but both without communicating with one another since they are in different subnets. "I want them to be able to communicate".

hi!
first of all you don't need mask of 255.0.0.0. It is HUGE subnet. It would be sufficient to have 255.255.255.0 mask.
only after that we can take subnet 10.0.0.0/24 (/24 means 255.255.255.0 in CIDR notation) and use it for PCs behind cisco eth0. Eth0 with ip of 10.0.0.1 will be dafault GW for all PC behind him.
access list 1 leave as is.

D-link router can have 10.0.0.11/24 as wan address, and let's say 10.0.1.1/24 as lan address. so wireless clients will get addresses from 10.0.1.2-254 subnet.

now the tricky part, you have tried to do, but with no success: you need a static route on cisco to 10.0.1.0/24 subnet.
ip route 10.0.1.0 255.255.255.0 10.0.0.11 should do the thing.

after that your cisco will be able to privide internet to both wifi and wired PCs and your wired PC will be able to access wifi PCs.

Thank hostarica,
I've done that in the past, but unfortunately thats not an option for me at this moment.
Will have to figure out the subnet commutation, with the 10.20.30.40 d-link to the 10.0.0.1 cisco device, some how there is an answer.

I don't want to change wireless LAN IP, I want it to stay as 10.20.30.40, and it has DHCP which is assigning from 41 to 60.

hi rr100, my apologize, but to my solution I have forgot to mention, that you have to disable NAT on d-link. so yes, you are using dlink's wan port to connect it to cisco, but you don't use NAT (Network address translation).
do you have default gw on d-link configured to 10.0.0.1? what mask do you have on d-link's wan address?

rr100, I've got manual for D-Link WBR-1310 now and it seems there is no option to disable NAT. It means PCs from behind cisco will be unable to reach wireless PCs. If you still don't want to use hostarica solution, then then only thing we have to solve here - is internet availability for wifi users.
btw, right now, wifi users should be able to ping 10.0.0.1 and PCs behind cisco.

As has been described here, I don't know that you can get this to function the way you want. You can certainly use the Dlink as an access point on the same network, but you can't segment it out. You probably could with a different router (cisco), but I'm pretty sure that Cisco doesn't allow multiple networks to be configured behind it (i.e. subinterfaces). Quick test of that would be to try:

Router(conf)# int ethernet1.1

If so, you could setup sub interfaces, set the dlink to AP mode, and assign your ranges that way... but I doubt it.

Otherwise, without static routes or a dynamic routing protocol, you won't be able to setup routing between networks that are behind separate routers.
